Tinea versicolor is a long-term (chronic) fungal infection of the skin.
Tinea versicolor is fairly common. It is caused by a type of fungus called Pityrosporum ovale. This fungus is normally found on human skin. It only causes a problem in certain settings.
The condition is most common in adolescent boys and young adult men. It typically occurs in hot climates.
The main symptom is patches of discolored skin that:
African Americans may have a loss of skin color or an increase in skin color.
Other symptoms include:
Your health care provider will examine a skin scraping under a microscope to look for the fungus.
The condition is treated with antifungal medicine that is either applied to the skin or taken by mouth.
Applying over-the-counter dandruff shampoo to the skin for 10 minutes each day in the shower is another treatment option.
Tinea versicolor is easy to treat. Changes in skin color may last for months. The condition may come back during warm weather.
Call your health care provider if you develop symptoms of tinea versicolor.
Avoid excessive heat or sweating if you have had this condition in the past. You can also use anti-dandruff shampoo on your skin every month to help prevent the problem.
